My Aunt has been known to go through my things as a young boy, checking for drugs, alcohol, ect (which I'm proud to say I never had). I can kind of understand her doing this when I was 12 or 13, but now at the age of 18 she is very often looking over my shoulder when I'm on my pc, even if this means entering a room where I am quietly revising or programming my websites to do so. I have also noticed times when it has been obvious she wants me out of the room for some reason. I have even caught her touching my pc at one point ready to open it and then suddenly 'move it out of the way' in a 'damn I've been caught' sort of way.
I have nothing to be ashamed of on my PC but I don't feel comfortable with her possibly trying to go through it, especially as I am 18 now. If say she has/is/or will go through my pc checking various things, is this technically breaking the law in any way?
